Our Time and Labor Management module simplifies labor-intensive time and paid-time-off tracking, data entry, and approval processing. It is design for the mobile workforce where, in a given week or pay period, employees and contractors work multiple job assignments, multiple clients and projects, work in multiple tax jurisdictions, and record labor across complex organization structures.  

Key Features:

  • Record employee hours and across multiple job assignments with different pay rates
  • Distribute employee hours, wages and one-time deductions across multiple tax jurisdictions
  • Distribute employee hours, wages and one-time deductions across multiple organizations, clients and projects 
  • Incremental employee shift differentials computed automatically
  • Make-up wages for tipped employees computed automatically
  • Supports multiple paid-time-off hours and accrues leave automatically across multiple plans


Our Payroll module is robust, accurate, reliable and fast. When you 'Run A Payroll', payroll is processed as well as all agency obligations are generated and scheduled. In a single click the Payroll Register, ACH Deposits Register, Agencies Payable and General Ledger Transactions are ready for review. Timesheet, employee and agency changes can be applied before the results are 'Approved' for disbursement and back office administration.

Key Features:

  • SeriousPayroll supports 10,000+ tax jurisdictions.
  • On-Demand paychecks can be generated at any time.
  • Wage garnishments comply with the Federal Wage Garnishment Law,  Consumer Credit Protection Act's Title 3.
  • Processing a payroll of 500 employees complete with multiple tax jurisdictions, multiple paychecks per employee, and general ledger distribution, is accomplished in less than 30 seconds. REALLY! 


Our platform streamlines accounts payable by seamlessly integrating agencies payable into 'Run A Payroll'. Based on payroll withholdings and employer matching or partial matchings for withholdings, SeriousPayroll automatically assembles and schedules agency obligations. Payroll taxes, insurance benefits, defined contributions, wages garnishments, union dues and any other employer-designated agency obligations are scheduled for payment according to the semi-weekly, monthly, quarterly or other deposit frequency set up for those agencies. 

Key Features:

  • Agencies payable can be printed as checks or ACH CCD deposits.
  • On-Demand Paychecks automatically assemble and schedule corresponding agencies payable.
  • Voided Paychecks automatically assemble and schedule corresponding agencies payable reversals.
  • Agency checks are merged with employee paychecks for payment reconciliation. 


Our platform’s Employee Self Service feature is designed to allow employees to participate in payroll administration and time and labor management in a way that tremendously reduces the work load of the payroll department. Employee participation is effective but does not jeopardize security and accuracy.

Key Features:

  • Employees can update basic information on their profile, maintain an unlimited number of ACH bank deposits and edit timesheet entry.
  • View Paid-Time-Off accrued, taken and available.
  • View Paystubs from any timeframe.
  • View and Print Form W-2 for any calendar year.
  • View and Print Form 1099-MISC for any calendar year.
